We show that our gender-specific crosswalk more accurately captures the trends in occupational segregation that are masked using the aggregate crosswalk (based on combined male and female employment) provided by the U.S. Census Bureau. Using the 2000 occupational codes, we find that segregation by sex declined over the period but at a diminished pace over the decades, falling by 6.1 percentage points over the 1970s, 4.3 percentage points over the 1980s, 2.1 percentage points over the 1990s, and only 1.1 percentage points (on a decadal basis) over the 2000s. A primary mechanism by which occupational segregation was reduced over the 1970-2009 period was through the entry of new cohorts of women, presumably better prepared than their predecessors and/or encountering less labor market discrimination; during the 1970s and 1980s, however, there were also decreases in occupational segregation within cohorts. Reductions in segregation were correlated with education, with the largest decrease among college graduates and very little change in segregation among high school dropouts. aHardcopy version available to institutional subscribers aSystem requirements: Adobe [Acrobat] Reader required for PDF files. aMode of access: World Wide Web.0 aPrint version record 7aJ16 - Economics of Gender • Non-labor Discrimination2Journal of Economic Literature class. 7aJ24 - Human Capital • Skills • Occupational Choice • Labor Productivity2Journal of Economic Literature class. 7aJ62 - Job, Occupational, and Intergenerational Mobility2Journal of Economic Literature class. 7aJ71 - Discrimination2Journal of Economic Literature class.1 aBrummund, Peter.1 aLiu, Albert Yung-Hsu.2 aNational Bureau of Economic Research. 0aWorking Paper Series (National Bureau of Economic Research)vno. w17993.40uhttp://www.nber.org/papers/w1799340uhttp://dx.doi.org/10.3386/w17993
